In an effort to decrease the mAs of an exposure, the 15% rule of kVp change may be considered.Changing the original kVp of 84 using the 15% rule will have what impact?

Question

Quizplus · Accepted Answer

According to the 15% rule, a 15% decrease in kVp would result in a doubling of the number of Compton scatter interactions. Therefore, decreasing the original kVp of 84 by 15% would result in greater Compton scatter interactions. It could potentially lead to lower contrast but may be beneficial in reducing patient dose. The options A and C are not directly affected by the 15% rule. The option D could potentially improve contrast but is not directly related to the 15% rule.
